Description

  The present invention relates to a roof safety equipment mounting bracket used as a safety rope (safety belt) or the like attached on a roof, and more particularly, does not damage tiles during use, and has tensile strength, pulling strength, durability, and water leakage resistance. The present invention relates to a roof safety equipment mounting bracket that is excellent in performance, easy to install and inexpensive.

  When working on high places such as on the roof, it is common for workers to secure their safety by wearing safety ropes. The safety rope is fixed temporarily or permanently to a safety equipment mounting bracket attached to a high place such as on the roof.

  As such a safety equipment mounting bracket, for example, as described in Patent Document 1, a wire rope having hook loops provided at both ends is used, and one loop is fixed under a roof tile, and the other A safety band mounting bracket having a structure in which a loop is taken out from between roof tiles and a safety rope is fixed to the loop that has come out has been proposed.

  Further, as described in, for example, Patent Document 2, a roof work safety metal fitting in which a ring metal fitting (shackle) is attached to a support column erected on a washer has been proposed.

  Furthermore, for example, in Patent Document 3, a fixing portion that is fixed to a field plate, a hooking portion that is hooked to an end of a tile bottom side, a connecting portion that extends in the eaves side direction, and an operator safety belt are attached. A safety fitting for a roof provided with a mounting portion is proposed.

However, since the wire rope itself extended from the bottom of the roof tile moves every time the operator moves, the safety rope mounting bracket of Patent Document 1 may damage the roof tile.
In addition, the safety bracket for work on the roof of Patent Document 2 has a high installation height, so that the pulling strength is inferior, and it takes time to mount the bracket. It includes the problem of poor workability.
Furthermore, since the roof safety metal fitting of Patent Document 3 has a large number of bent portions, the bending work takes time and cost, and the bent portions tend to extend, so that the tensile strength and the pulling strength are reduced. Furthermore, since the engaging member (eye bolt) for mounting the safety belt is provided on the mounting portion that is erected substantially vertically, the installation height is increased, and the pulling strength is further reduced in this respect.

  Furthermore, they all have the disadvantage that they can only be installed on the rafters, so that the safety rope cannot be secured to the part without the rafters. As a specific example, in the case of a corrugated roof tile or the like, there are few metal fitting positions that can be installed on the roof tile, so there is a problem that the rafter position is often different and the metal fitting cannot be installed.

  In view of such circumstances, the present invention eliminates the problems of the prior art described above, does not damage the roof tiles during use, has excellent tensile strength, pulling strength, durability, and water leakage resistance, and the position of the bracket and the rafter are misaligned. However, it is an object to provide a roof safety equipment mounting bracket that is easy to mount and inexpensive.

  Still another feature of the present invention is the above-described roof safety equipment mounting bracket, wherein the safety equipment mounting portion is an eye strap attached to the extension portion.

  Still another feature of the present invention is a roof structure in which the roof safety equipment mounting bracket is attached to a tile roof, wherein the base plate fixing portion is fixed to the base plate by fixing means, and the extension portion is directed toward the eave side. It is arrange | positioned between an upper roof tile and a lower roof tile, and is the roof structure characterized by the safety equipment attachment part of the extension part being exposed.

  The roof safety equipment mounting bracket of the present invention has a structure in which a simple plate-like field plate fixing portion and an extension portion are formed in a T shape, so that the roof plate fixing portion and extension portion are not damaged during use. Since both can be fixed, the tensile strength and pulling strength are high. Also, even if the bracket position and rafter position are misaligned, if you fix any part of the horizontally long base plate fixing part, you can secure the tensile strength and pulling strength, so place the safety equipment mounting part at a position other than the rafter be able to.
